Answer:

a K=2

b A =200

c B = ±2

Step-by-step explanation:

A = kB^2

When A =50 B=5

Substitute these values in

50 = k * 5^2

50 = k*25

Divide by 25

50/25 = k25/25

2 =k

A = 2B^2

When B = 10

A = 2*10^2

A = 2 *100

A = 200

When A =8

8 =2B^2

Divide by 2

8/2 = 2/2B^2

4 = B^2

Take the square root

±sqrt(4) = sqrt(B^2)

±2 = B

Solve the inequality. 2(4+2x)>5x+5 oxs-2 O X2-2 xs3 x23

mafiozo [28]

For this case we must resolve the following inequality:

$2 (4 + 2x)> 5x + 5$

Applying distributive property on the left side of inequality we have:

$8 + 4x> 5x + 5$

Subtracting 5 from both sides of the inequality:

$8-5 + 4x> 5x\\3 + 4x> 5x$

Subtracting 4x from both sides of the inequality:

$3> 5x-4x\\3> x$

Thus, the result is $x$

Answer:

$x$

Explain what needs to be fixed. 2n + 10 = -2 2n = 12 Step one n = 6 Step two

Brilliant_brown [7]

Answer:

step one needs to be fixed... you are supposed to subtract 10 from both sides of the equation.

Step-by-step explanation:

STEP 1: Move all terms not containing n to the right side of the equation.

$2n=-12$

STEP 2: Divide each term by 2 and simplify.

$n=-6$
